this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...

Fifteen yarrow populations from different species Achillea millefolium L., A. biebersteinii L. and A. nobilis, from different geographical areas of Iran were studied using 24 morphological traits and peroxidase profiles. Comparison of mean values of different phenotypic traits show A. millefolium and A. biebersteinii L. had higher plant height and crown diameter; however, A. nobilis had higher ...
